CUTTING APPLIANCE FOR VELVETS, PLUSI-IES, AND SIMILAR FABRICS.

Application filed May 12, 1908.

To all whom it may concern:

Be it known that I, PAUL HERTZOG, a subject of the German Empire,residing at Miinchen-Gladbach, in the Kingdom of Prussia, Germany, haveinvented a new and useful Cutting Appliance for Velvets,

Plushes, and Similar Fabrics, of which the following is a full andcomplete specification.

The subject of my invention is an appliance for cutting velvets, &c.,which may be fitted with any required number of knives, offset from eachother, for cutting the loops in successive lines of plushes, velvets orother similar material.

The cutting device is fitted with a contrivance which immediately putsout of operation any cutter or cutters which should fail to operatecorrectly.

The invention is shown on the accompanying drawing in one mode ofconstruction.

Figure 1 shows the cutting device in a side elevation and Fig. 2 is aplan view. Figs. 3 and at show the cutter block or carrier in positionfor cutting and also out of position, while Fig. 5 is a section to lineA. B. of Fig. 8.

In the mode of construction shown in the drawing, the blocks or carrierscl for the knives f which, as illustrated, may be secured in position bykeys h, are ofiset'from each other on the knife-holder bar a, which isof some light metal, pressed steel or iron for example. Theknife-holder, which is bent at one of its ends a and, for greater easeof manipulation, provided with a handle, carries the bolts 0 on whichare pivoted the blocks d. As shown in the drawing, a collar or washer t,with shoulders t may be employed for each knife-holder. The collars tare gripped by the claws of the retarding spring 71 which is fixed onthe knife block, the springs acting on the straight shoulders of thecollar and retaining the holder in its working position.

In case of accident while cutting, for example, if the cloth is pierced,all the damage Specification of Letters Patent.

that is done is that a small hole is made, as the knife holder is turnedaround or reversed by the piece running past and is held in its harmlessposition by the spring 2', which also engages collar 25, in the reversedposition of the carrier.

The knife carriers are preferably held loosely by the spiral springs eon the bolts or gudgeons 0, these springs pressing them against the boss0 of the bolt or gudgeon c, in order that, if the cloth happens to getslightly out of its course, the knives will follow it.

At the front of the knife holder, there is a guide or rest u, of thincopper wire for the purpose of keeping the cutting devices at the properheight.

Having now fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. A cutting appliance of the character described, comprising a bar, aseries of bolts projecting laterally therefrom, knife carriers set offfrom each other and rotatably mounted upon the bolts, knives secured tothe carriers, said carriers having flattened portions on the sidesopposite the knives, and springs secured to the bar and bearing uponsaid flattened portions.

2. A cutting appliance of the character described, comprising av bar, aseries of bolts projecting laterally therefrom, knife carriers set offfrom each other and rotatably mounted upon the bolts, coiled springsencircling the bolts and bearing against the carriers, knives secured tothe carriers, said carriers having flattened portions on the sidesopposite the knives, and leaf springs secured to the bar and bearingupon said flattened portions.
